We are currently coordinating with Shaw regarding a possible problem on providing DHCP DNS IP for our Cable customers wherein customers modem is online and getting a valid DHCP IP address on their devices but still cannot browse. Please do try to use Google's DNS IP 8.8.8.8 & 8.8.4.4 as an alternative and check if it will work. If it will work, please get the DHCP DNS IP customers device is automatically getting and file a ticket to in our ClientArea and state the problem with the DNS IP.
